2007.5-2010 GM Duramax 6.6L LMM Exhaust Kits
The 6.6L Duramax LMM under the hood of your 2007.5-2010 GM 2500/3500 throws down some impressive power and awesome low-end torque, but the factory exhaust system doesn't let others on the road know it. You can add tons of style and sound to your Sierra or Silverado with the addition of an aftermarket performance exhaust kit. These premium street-legal and off-road exhaust systems feature much more efficient designs over your restrictive factory system, allowing your engine to breathe easier. On top of their impressive power gains, these premium aftermarket exhaust kits provide an aggressive tone that will be sure to get the blood flowing each time you hop on the accelerator. We offer everything from single-exit kits, dual-exit kits, up-pipes, downpipes, and universal exhaust tips to get your entire exhaust system looking and performing the way you want it to!
